Licensing Process

WDC provides the CMOS 65xx Microprocessor family of GDSII Hard Cores and Verilog RTL Soft Cores which have been proven in high volume production of our standard product line.

Licensing Process

IP License Business Model

The WDC licensing business model is flexible and is a combination of licensing fees and royalties that can be negotiated at the time of licensing. Our Technology License Agreement (TLA) is available to those qualified potential licensees under an NDA. Once licensed, all required views of the technology are transferred under the TLA. Our IP has been proven in volume production standard products and various licensed ASIC products of our licensees on various pure play foundries for example UMC and TSMC at sub-micron geometries. In addition, several integrated device manufacturers have had significant success within their internal manufacturing facilities over the last 25+ years. WDC can retarget to specific process nodes or as a licensee you can retarget to any CMOS process node you desire.

W65C02S 8-bit Microprocessor (MPU)
The W65C02S is a low power 8–bit microprocessor utilized in a vast array of products for the Automotive, Consumer, Industrial, and Medical markets. This chip features a full external data (8–bit) and address (16–bit) bus for easy integration with 8–bit peripherals and memory.

W65C816S 8/16–bit Microprocessor (MPU)
The W65C816S extends the 65xx technology family to handle 16–bit processing with a 16MB memory space while its emulation mode allows complete hardware and software compatibility with 64KB 6502 designs. The New Direct Register and stack relative addressing provides capability for re–entrant, re–cursive and re–locatable programming.

W65C134S 8–bit Microcontroller (MCU)
The W65C134S is a feature rich 8–bit microcontroller based on the W65C02 with an advanced (originally designed for life support) Serial Interface Bus (SIB) token passing local area network for multi–W65C134S processor systems. The W65C134S has a full external memory bus (8–bit data and 16–bit address bus) for flexible system design. This MCU has an embedded debug monitor ROM with a library of routines that can help you reduce development time.

W65C265S 8/16–bit Microcontroller (MCU)
The W65C265S is the 16–bit extension of the 65xx microcontroller family. Along with increasing the memory space to 16MB with a full external memory bus (8–bit data and 24 bit address bus) for flexible system design, the W65C265S includes 3 additional UARTs, increased GPIO, Parallel Interface Bus, twin tone generators (can perform DTMF signaling) and more. Similar to the W65C134S, the W65C265S has a built–in debug monitor ROM and libraries. A reference design with OS kernel, display, ToD, data communications and power management software is available directly from WDC to ease system development.
